jarl,
I understand what you are talking about... The column pin for the shift indicator is simply out of line... Its merely a string with a pointer that can be adjusted...
as for the issues you are seeing on the tool with the with the van being in and out of park for no reason has more to do with a bad Park Neutral safety Switch on top of the transmission... The PCM uses this to determine if you have selected Park/ Neutral or Drive.... The starter circuit also passes through the switch...
As for the stalling in the driveway will it restart right away? also did you by chance have a Code 361 or 1361? I think you are having a PCM issue but would like to know if you have the above codes...
